Obsidian was used to make tools and luxury items which were widely distributed in the ancient Near East. At most sites it is an imported material and, as such, has been used as an indicator of exchange, although little specific detail of the nature of that exchange is available. Even though methods of provenance analysis for obsidian are well established, often only a few samples per site have been analysed. This means there is not enough information to indicate the relative importance of the obsidian from each source, or to establish whether source preference changed through time or whether obsidians from different sources were treated differently. The restriction in numbers analysed is, at least in part, due to the expense and the destructive nature of provenance analysis and problems associated with obtaining sufficient samples. In an attempt to address these problems case-studies examining the obsidian assemblages from three sites of Halaf date will be used to demonstrate the potential of a method of grouping obsidians based on their physical characteristics, including colour; these groupings are confirmed by geochemical analysis. This allows the entire assemblage to be grouped quickly and cost effectively and, if used alongside techno-typological and spatial studies, enables us to begin to confront some of the issues outlined above.
OzetObsidyen, ornekleri Yakin Dogu'da geni § bir bolgeye yayilmis, olan aletlerin ve liiks tiiketim uriinlerinin yapiminda kullamlan bir malzemedir. Bolgedeki takas sisteminin yapisina dair bilgilerimiz az olmakla birlikte, obsidyen binjok yerle §imde ithal bir malzeme olmasi nedeniyle takasin varhgina i §aret eder. Geli §mi § obsidyen kaynagi analiz yontemlerine ragmen, her yerlegimden c;ogu kez sadece az sayida ornegin analizi yapilabilmi §tir. Bu nedenle elimizdeki bilgiler, digerlerine kiyasla tercih edilen obsidyen kaynaklanm saptamak, zaman icinde tercihlerin degisip degismedigini ya da farkh kaynaklardan gelen obsidyenlerin farkli bicimde iglenip i §lenmedigini anlamak icin yeterii degildir. Analizi yapilan ornek sayismin sinirli olmasinin, en azindan kismen nedeni kaynak analizinin pahali bir i §lem olmasi ve analiz sonunda ornegin iglemin do §asi geregi yok olmasidir. Aynca yeterii miktarda ornegin bulunmasiyla ilgili problemler de bu durumun bir nedenidir.

Bu gruplamalar jeo-kimyasal analizle de dogrulanmaktadir.
